Place the lime peel in a highball glass and add the gin. Muddle the lime peel gently, to help press out some of the lime oil. If you're patient, let it sit in there for a few minutes. Then fill the glass almost to the top with cracked ice cubes. Add the lime juice. Fill with the tonic water, then add the bitters (don't be shy). Rub the lime wedge around the rim of the glass, then add it as a garnish. Swizzle, then serve the drink with the swizzle stick. Accept the compliments graciously.
